Sneak peak of tonight's Mad Men

Betty Francis (formerly Betty Draper) has always been an ice cool blonde so this picture of the character, played by actress January Jones, is a bit of a surprise. What do you think of brunette Betty - let us know in the comments below.

As well as Betty's surprising dye job we've also got a picture of Megan Draper (Jessica Pare) in a wonderful late Sixties' bikini and Joan Harris (Christina Hendricks) also looking very of the time in purple ruffles.
